T The. turning of the pinionas the machine is drawn ever the groundactw ates the-cutter bar 20, byany suitable means, but preferably hy means of a crank 29 mounted on thesame shaft as the pinion 27, thisicr'anlr actuating a 30 connected to'of'the lever ,being' in engagement withthe putter bar-bymeans of. apin'and slot con: ,nection 32. .This. lever isjpi rotallyimounted atan'intermediate point in enter-tempesings' 40 inthe lug ll' carriedbyitlie: arr-1t Hi:

The pIat'eQ is majntainedjin its outer i position with thepiniongfiiinengagement with the teeth 9 by meansgoi a'suitatf" 1 spring33, one end of'whichfis 'secure 'li gone-0f the arms 16, the other beingits; engagement with a, lug ll earriedby-the plate As the machine ismmabver the ground the, -.r )tation of the wheel 8 will turn the 30 andthe letter 3%, thereby reciprocating from one of the a tapering openingextendlng therethrough,

the cutter bar, this bar together with the --l guard fingers on bar 21extending downby the post 54 the quadrant v51 being suit ably supportedon the frame 1. The upper end of the post is provided with a pulley 57,the cord or chain 52 having one of its ends secured to the lever at 58and passing over this pulley, the other end being secured to the post 51 at 55. Extending longitudinally of the supporting member is anothercord or chain 58 having one end. secured at 57 to this member, the otherend being secured at 39 to the plate 24. A pulley 56 is suitably secured.to the cord 58 at a point intermediate of its length, thebeforementioned cord 52 passing around the pulley. The height of thepost 54 and the length of the lever and cord 52 is such that by pullingbackwardly on the lever the arms 16 are elevated, thereby carryingthccutter bars away from the, ground, movement of the lever also moving theplate 2a which brings the pinion 27 out of engage- 1 ment with the teeth9 on thetraction wheel 8.

It is to be particularly noted that the cut ting mechanism is hingedlysuspended on the ends 18 of the arms 16, these arms being movablymounted on the axle 7 so that a limited movement of one arm relativelyto the other is freely permitted whereby the machine goes over theground one end of the cutter bars may lie at a greater or lesser heightthan the other end, thereby providing for eflicient operation on rough,

irregular ground.

Since the cutting device 19, at the. forward ends of the arms 16, ishingedly mounted in position, it is desirable that the position thereofbe fixed when the machine is in use and to this end- I provide suitablemeans; pivoted to and extending upwardly arms 16 is a post 60 havinginto which one end of the brace 61 extends; the thickness of the braceis greater than the width of one end of the opening and less than thewidth of the other end thereof. The forward end 62- of the brace issecured to the cutting device as shown in Fig. 1

and, by securing theupper end of the. brace 23, the cutting mechanism towhich it is attached may be determined the upper end of the brace 23being adapted to be frictionally held. secured within the taperingopenmg inthe lever 60 whereby the adjustment of the-parts may be quicklyobtained.

In the operation of the machine through soft groundthe teeth 9 on theinside of the wheel's may become filled with soil andin order to preventorlessen this I make use of a suitable cover\63 secured at the outerends of suitable arnis--6-t which have their upper ends in engagementwith the axle 7: this cover 63 is preferably, of the shape shown in Fig.1, the curvature of the sides thereof being equal to that of the wheel 8so that as the wheel is drawn over the ground the entrance of soil intothe teeth is prevented, the operation of the cover being facilitated,possibly, by providing the inside of this wheel 8 with a peripheraltiange 65 against which the lower side of the cover closely fits.

Ase-at 100 is preferably provided on the supporting frame 1, thelocation of the seat being adjacentthe regulating mechanism of theengine and also in close proximity to the steering wheel 1 1 and thelever and ratchet 50 in order to bring the means for controlling all ofthe parts of the machine within the grasp of the driver. The size of thedifferent parts may be varied and the material of which they are madewill depend largely upon the finish of the machine desired, such changesbeing included in the spirit of the appended claims.

Having thus described my invention, I claim new, and desire to secure byLetters Patent Y 1.
